Starch/polyaniline nanocomposite for enhanced removal of reactive dyes from synthetic effluent

► Starch/polyaniline nanocomposite - an eco-friendly polymer matrix for the treatment of dye bath effluents. ► The nanocomposite decolorized 87% of dye bath effluent. ► The removal of dyes is largely depending on the solution pH. ► The removal process followed Freundlich isotherm and pseudo-first order kinetics.
